Abstract

The utility model discloses a strong rammer with a circular arc bottom, and belongs to the field of rammers. The strong rammer comprises a rammer body, a rammer cover welded at the upper end of the rammer body, and shaft lugs and a hanging shaft which are fixed on the rammer cover, wherein the rammer body is solid, and the bottom surface of the rammer body is a circular arc surface; a plurality of large air exhaust holes evenly distributed in the circumferential direction and a plurality of small air exhaust holes arranged among the large air exhaust holes at intervals are formed on the circular arc bottom surface of the rammer body; a plurality of large air exhaust holes and small air exhaust holes which are evenly distributed in the circumferential direction and corresponding to the bottom surface of the rammer body are formed on the rammer cover; and concrete is poured into a hollow cavity of the rammer body. The large and the small air exhaust holes on the rammer body are matched with the circular arc bottom of the rammer body to achieve an air exhaust effect, so that safety hazards brought by flying rock caused by air weaves produced when the strong rammer hits the ground can be reduced. The strong rammer has the beneficial effects of simple structure and is convenient to implement; and the foundation ramming effect is effectively improved, and the hidden dangers caused when the strong hammer descends are reduced to the greatest degree.

Description

Strong hammer ram at the bottom of a kind of circular arc

Technical field

The utility model relates to strong hammer ram at the bottom of a kind of circular arc, belongs to the hammer ram field.Be mainly used in the operation of building engineering construction compacting foundation, reduce corresponding potential safety hazard.

Background technology

In construction work, need compacting foundation, the compacting instrument that uses at present is traditional strong hammer ram.Because the bottom of traditional strong hammer ram is flat; Tilt easily during the whereabouts and ram partially, be difficult for guaranteeing the quality of compacting, can cause that mincing of ground splash because strong hammer ram produces blast when landing simultaneously; Bring potential safety hazard easily, damage for ground staff.

Utilize at the bottom of the circular arc strong hammer ram can active set in hammer body own wt compacting foundation, can reduce the generation of the blast that produces in the strong hammer ram dropping process at the bottom of the circular arc simultaneously, and can in time blast be discharged through pore.

Summary of the invention

For overcoming the above-mentioned deficiency of prior art, the utility model provides strong hammer ram at the bottom of a kind of circular arc, is used for improving compacting efficient, and farthest reduces the blast that strong hammer ram falls to producing and impact the potential safety hazard that causes.

The utility model is realized with following technical scheme: strong hammer ram at the bottom of a kind of circular arc, comprise hammer body, and be welded on the hammer lid of hammer body upper end, be fixed on axle ear and hanging axis that hammer covers; Described hammer body is hollow hammer body, and its bottom surface is an arc surface; Having a plurality of circumferentially equally distributed big steam vents and a plurality of interval small de-air hole between big steam vent on the arc surface bottom surface of hammer body; Cover at hammer and to be distributed with circumferential equally distributed a plurality of big steam vents and the small de-air hole corresponding with the hammer body bottom surface; In the cavity of hammer body, built concrete.

The beneficial effect of the utility model is that simple in structure, convenience is implemented; Effectively improve the compacting foundation effect, the blast that has farthest reduced the whereabouts generation of strong hammer ram impacts the potential safety hazard that causes.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the utility model front view;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the sectional drawing of Fig. 1;

Fig. 4 is the vertical view of Fig. 1.

Among the figure: 1, hanging axis; 2, hammer lid, 3, the axle ear; 4, hammer body, 4.1, big steam vent, 4.2, small de-air hole, 5, concrete.

The specific embodiment

Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, strong hammer ram comprises hammer body 4 at the bottom of a kind of circular arc, is welded with hammer in hammer body 4 upper ends and cover 2, is welded with an ear 3 and hanging axis 1 on 2 hammering into shape to cover; Hammer body 4 is hollow hammer bodies, and its bottom surface is an arc surface; On the arc surface bottom surface of hammer body 4, have 4 circumferential equally distributed big steam vents 4.1 and 4 intervals small de-air hole 4.2 4.1 of big steam vents; Cover and be distributed with circumferential equally distributed a plurality of big steam vents and the small de-air hole corresponding on 2 at hammer with the hammer body bottom surface; In the cavity of hammer body 4, built concrete 5.

Like Fig. 1, shown in Figure 2, the hanging axis 1 of this strong hammer ram is a circular arc, and axle ear 3 has two, is positioned at hanging axis 1 both sides, hanging axis 1 and axle ear 2 interference fit; When being convenient to grasp, make hammer body keep balance.Axle ear 3 is welded on hammer and covers on 2 the upper surface.

As shown in Figure 3, actual fabrication is: behind the concreting 5, the side of each hole wall and hypophysis 4, bottom surface form cavity, again hypophysis 4 are covered 2 with hammer and weld together in the cavity of hammer body 4.

Because hammer body 4 bottom surfaces are arc surface; When compacting foundation, weight concentrates on than on the small size, more helps compacting; Cooperated scavenging action at the bottom of large and small steam vent on the hammer body 4 and the circular arc, the potential safety hazard that the slungshot that the blast that produces in the time of can reducing strong hammer ram colliding surface causes brings.
